To verify the beneficial effects of the multifunctional skin cream of the present invention, the following tests were conducted.

First, anti-wrinkle and anti-aging efficacy test

Testing the population: the multifunctional skin care cream prepared in the embodiment 1 of the invention is used twice in the morning and at night every day in the test of 50 persons and female testers of 40-65 years old.

Testing parameters: wrinkle depth, skin firmness, skin elasticity. The results of the test using the skin elasticity tester MAP580 after two consecutive months are shown in table 1 below.

Table 1: skin change in anti-wrinkle and anti-aging efficacy tests

Skin Properties	Compared with before use
		Wrinkle depth reduction	15.7％
Increased skin firmness	18.2％
		Skin elasticity increasingAdding	7.6％

As can be seen from the results in Table 1, the multifunctional skin care cream provided by the invention can be used for keeping moisture for a long time, repairing dry and rough skin, moistening and softening skin, delaying skin aging, tightening skin, enhancing skin elasticity and reducing wrinkles.

Test two, whitening efficacy test

50 female volunteers aged 20-40 years are selected for testing, the indoor temperature is kept at 25 ℃, the relative humidity is kept at 55%, the multifunctional skin care cream prepared by the invention is coated on the bent parts of the left and right forearms of the volunteers and is continuously used for 28 days, the melanin indexes MI of the test positions at the initial, 7, 14 and 28 days of the test are respectively measured by a skin melanin and heme tester (Mexameter MX18), and the average value is calculated, and the results are shown in Table 2.

Table 2: melanin index MI test result condition in whitening efficacy test

As can be seen from the results in Table 2, compared with comparative examples 1 to 4, the melanin index MI tested in examples 1 to 3 is lower, and therefore, the multifunctional skin care cream has a better whitening effect. The whitening effect of the multifunctional skin care cream is the best in example 1, and the whitening effect of the multifunctional skin care cream obtained finally is poor due to the fact that the active ingredients are not partially contained in the comparative examples 1-4, and the fact that the sturgeon caviar extract, the shea butter, the glycyrrhiza glabra root extract, the emblic leafflower fruit extract and the lipid complex are used in a specific ratio shows that the multifunctional skin care cream has a synergistic effect and the whitening effect is improved.

Third test, skin repairing efficacy test

Taking 7 groups of samples of the multifunctional skin care cream prepared in the examples 1-3 and the comparative examples 1-4, selecting 70 female testers with sensitive skin to carry out the effect use evaluation of sensitive skin repair, wherein 7 female testers in each group of samples are scored and averaged, the score is 10, the score of 10 is the best sensitive repair effect, the score of 9 is the lowest, and the score of 1 is the worst sensitive repair effect. The composition was administered twice daily for 10 consecutive days, and the results are shown in Table 3 below.
